From white paint on a mural to "black power" on a monument. The likenesses of former Mayor Frank Rizzo under assault this week. Over the phone, his son, Frank, Jr. reacts.

"It bothers me to see things like this happen but in any instance you have to remember it's one or 2 people. It's not a majority," he said.
